UNITED STATES LEON J. HARVEY, OF PLOVER, VISOONSIN.

GRAIN-SCOURER.

ELFECEFICATION forming part of Letter-s Patent No. 323,035, dated July 28, 1885. Application filed April 23, 1835. (No modclJ To all whom, it may concern:

Be it known that I, LEON J. HARVEY,a citizen of the United States, residing at Plover, in the county of Portage and State ot Visconsin, have invented certain new and useful Improvement-s in Grain-Sconxers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a vertical sectional view ol'a grain-scouring machine embodying my improvements. Fig. 2 represents a crosssectional view on the line c x of Fig. 1. Fig. 3 is a detail of one of the beaters. Fig.l 4 is a detail in perspective of the inner cylinder, showing the beaters and means for adjusting thesame.

My invention relates to grain-scourers; and it consists in the construction and combinations of devices hereinafter described and claimed.

To enable others skilledin the art to make and use my invention, I will now describe the exact manner in which I have carried it out.

In the said drawings, A represents a frame of usual construction, in which the various working parts of my machine are mounted.

B represents a vertical shalt suitably mounted in the cross-pieces a a', and provided with a band-pulley, b, and a gear-wheel, c, which, operated by said vertical shaft, revolves the outer cylinder, G, as I shall hereinafter fully describe. l

Vithin a suitable casing, C, in the upper part of the frame A, is mounted asuction-fan, D. This fan receives its motion from the shaft B, and it has a direct connection with the interior of the cylinder through the medium of tlues connecting with the fan D through openings f, formed in its sides and terminating in vertical tlues c, which enter the cylinder-casing, as shown in Fig. 1.

E represents a vertical shaft, the lower end of which has a bearing in a step or cross-bar, g, and the upper end passes through and is permitted to revolve in a cross-bar, g', in the upper portion of the frame. Upon the shaft E is rigidly mounted a cylinder, F,which consists, essentially, of the end disks, h and 7L', and vertical beaters h?. The disk 7L receives the grain upon its upper surface, and is provided with a series of pins or lugs, t', which engage and evenly distribute the grain during the rotary movement of the cylinder. The beaters It?, which constitute a portion ot the cylinder, are secured to the end disks atan angle ordiagonally tothe outer revolving cylinder, G, and they are secured so as to have an adjustment toward or from the exterior cylinder,this adjustment being made to accommodate different kinds of grain. This adjustment is accomplished by the mechanism illustrated in Fig. 4. In this figure, it will be observed, the beaters h2 are attached to the end disks, It h', by pins 2, which permit the beaters to swing in or out. There is then placed inside this cylindenabout halt' way,a collar,B,with arms or pins 3, projecting into each beater, and with a hub which sets on the lower disk, h, and as the collar is turned the arms or pins 3 move the beaters toward the outer cylinder. This collar B is held in place by a set-screw, 5, at the lower end, the set-screw being made accessible by hand-holes 6 in the bottom of the cylinder and the openings in the outer cylinder which discharge the grain. The beaters h2, when set diagonally, as in the present case, have a tendency to retard the falling grain. The beaters h2 are corrugated their entire length, and the spaces between the beaters are equal to about one-half their width. These dimensions I prefer to use in the construction of my machine, although they may be changed without departing from the spirit of myinvention. The outer cylinder, G, has a hollow sleeve, H, and adisk, I, secured to said sleeve. A gear-wheel, K, secured to the outer cylinder forms the upper end of the cylinder, and this gear-wheel meshes with and receives its motion from the gear c on the vertical shaft B.

Extending upwardly from the gear K is another hollow sleeve, L,which engages the bottom of a suitable hopper and permits the grain to pass between the shalt and -sleeve L and thence through the center of the gear to the distributer-disk.

The cover for the outer cylinder consists of the strips M, which are perforated their entire length with elongated slots m, and on their inner peripheries are formed with vertical corrugations n, as shown in Fig. 2.

Around the inside of the outer cylinder, and projecting inwardly a slight distance, are suit- IOO able flanges, Z, which prevent a too rapid descent ofthe grain through the machine, and the bottom disk, I, has aseries of openingsg, through which the grain passes, after it has been scoured, by being thrown centrifugally against the sides of the corrugated outer cylin der. The grain falling into the chutes O, directly beneath the disk, is discharged into 'a suitable receptacle.

The operation ofv my machine is as follows: Motion is imparted to apulley, P, on the shaft E, which operates the inner cylinder, F, and band r communicates the motion of shaftEto the shaft B, which operates the suction-fan D and gear-wheel c. The gear-wheel c, engaging the gear K.causes the outer cylinderto revolve, but in a direction opposite to the revolution ofthe inner cylinder, which is fast upon the shaft. This being the case, the grain which passes through the upper sleeve of the outer cylinder is discharged upon the top of the inner cylinder, receives a scouring by the opposite revolutions of the cylinders, and is discharged froin the machine in a clean condition. The chaff and light foreign substances, being carried upward by the suction, may be discharged in the usual manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a vertical outer cylinder having a gear-wheel, K, of an inner cylinder revolving in a direction opposite to the rotation ofthe outer cylinder and provided with a hollow sleeve, H, and the adjustable beaters h2, the pinion c, shafts B and E, and

means for operating the shafts, substantially as described.

2. The combination, with an outer cylinder having its circumference slotted its entire length and provided with an interior corrn gated surface and the horizontal {ianges Z, of an inner oppositely-revolving cylinder having a sleeve, H, supported in the frame of themachine, and the corrugated adjustable beaters h2, the inclined chutes upon each side of the sleeve O, the gears c and K, the shaftsB and E, and means for operating said shafts, substantially as herein described.

8. The slotted vertical cylinder G, having a hollow sleeve, L, through which the grain passes from the hopper, a gear-wheel, K, and

a perforated disk, I, forming the lower end of said cylinder, in combination with an inner cylinder having the end disks, hlt', the adjustable corrugated beaters h, ahollowsleeve, H, supported in the frame, and means for driving the cylinders in opposite directions, substantially as herein described.

4. A grain-scourer comprising the frame A, shafts B and E, gears c and K, the cylinders F and G, adjustable beaters, a suction -fan mounted on the shaft B, a fan-case having a discharge-opening, and the horizontal and vertical ilues d ande, the latter communicating with the interior of the frame outside of the cylinder G, substantially as herein described.
